Add to cart Mountain High EDS O2D1 Oxygen System $895.00 This is the basic Pulse-Demand Oxygen system used by paragliders and hang gliders. This kit comes with the XCR primary reducing regulator, low-pressure service line, and the EDS unit and the breathing cannula and face mask. The low-pressure service line is a high quality polyurethane line that is kink-resistant and flexible under varying temperatures. The cannula, face mask and service line connect to the EDS unit via color-coded “Quick-Connects” providing an air-tight fitting by hand. These fittings can be connected and disconnected many times. The unit is very easy to use, and the instructions are well written. You can set your unit to begin releasing oxygen at a desired altitude. We recommend flying with the nasal cannula. The EDS system senses the pressure change when you inhale, and releases a dose of O2 making for a very efficient system. You will stay warm at altitude, and make better decisions on your flights with a good oxygen supply.
